The inheritance of siliqua strength was studied in Brassica campestris L. using F1, F2, and backcross generations of crosses between cv. Torch (shatter susceptible) and var. Yellow Sarson and var. Brown Sarson (shatter resistant) accessions. Shatter resistance (high siliqua strength) was recessive in all crosses. Crosses involving DS-17-D (var. Brown Sarson) indicated that siliqua strength is most likely controlled by two genes that show dominant epistatic interaction. Crosses of IB-5 and B-46 (both var. Yellow Sarson) each with cv. Torch indicated the likelihood of three genes controlling siliqua strength, two of which appeared to be epistatic over the third gene when dominant. In these crosses, the multivalve character appeared to be controlled by three genes, two of which were epistatic over the third gene resulting in multivalve character when the former two were recessive. Segregation for siliqua strength in the var. Yellow Sarson crosses was not independent of segregation for multivalve character.Key words: Brassica, siliqua strength, shatter resistance, Sarson.

Reciprocal crosses were made between a plant of Brassica campestris L. containing no erucic acid in its seed oil and two plants of the Indian varieties Yellow and Brown Sarson grown from seed containing approximately 59% erucic acid. The erucic acid content in the oil from F1 embryos was intermediate between the parents indicating embryonic control of the synthesis of this acid. Seed oil analysis of F2, F3, and backcross populations supported the hypothesis that erucic acid synthesis is controlled by a single non-dominant gene. Analysis of oil extracted from immature and partially germinated seed showed that erucic acid content was highest in fully matured non-germinated seed.

Genetic data on three asynaptic mutants showed that all are monogenically controlled by recessive genes. Differences in cytological abnormalities suggested that each mutant was controlled by a separate gene. The symbol, as, is proposed for these characters with the designations, as, as2, and as3.The degree of asynapsis varied from complete failure of pairing in two of the mutants to partial asynapsis in the third. Other aberrations, such as chromosome fragmentation, lagging, attenuated univalents, micronuclei, restitution nuclei, and aberrant sporad formation were observed. The value of these asynaptics in breeding and cytogenetic research is discussed.

SummaryAn experiment was conducted during the rabi seasons of 1980–1 and 1981–2 to study the effect of exchangeable sodium percentage (ESP) of 87, 62, 44, 34 and 27 on growth, yield and chemical composition of toria (Brassica campestris var. Toria), raya (Brassica juncea L.) rapeseed (Brassica campestris var. Brown Sarson) and taramira (Eruca saliva). Number of branches per plant, number of siliquae per plant and seed yield of these crops were highest at 27 ESP. Increasing ESP decreased N, P, K, Ca, Mg, Fe, Zn, Cu and Mn concentrations and decreased that of Na in seed and stover. These crops can be grown successfully up to about 44 ESP without significant reduction in yield. Raya and rapeseed produced higher yields than the other oilseed crops on sodic soil.

Rapeseed-mustard crops in India comprise traditionally grown indigenous species, namely toria (Brassica campestris L. var. toria), brown sarson (Brassica campestris L. var. brown sarson), yellow sarson (Brassica campestris L. var. yellow sarson), Indian mustard (Brassica juncea L. Czern and Coss.), black mustard (Brassica nigra) and taramira (Eruca sativa/ vesicaria Mill.), which have been grown since about 3,500 BC along with non-traditional species like gobhi sarson (Brassica napus L.) and Ethiopian mustard or karan rai (Brassica carinata A. Braun).
